Chemistry and Counterfeiting - A TED-Ed Lesson

How to Spot a Counterfeit Bill is a fun TED-Ed lesson about money. In the lesson students learn about the chemistry of counterfeit detection. In other words, they learn why and how those highlighter pens work on when a store clerk runs one over a twenty dollar bill.

The lesson on counterfeiting could pair nicely with another TED-Ed lesson about the value of money. What Gives a Dollar Bill Its Value? is a nice TED-Ed lesson on the influence of the United States Federal Reserve banks on the value of currency. The lesson includes a short piece about the correlation between inflation and the overall health of the U.S. economy.
